    Another point to remember on the return chamber. The auto topup switches are also kept here. Make sure that there is enough water between ATU switch and return pump for evaporation in case the ATU stopped working for some stupid reason. Pump must still be submerged by the time you get home. So have the ATU switches as high as possible in this chamber. Same for all other chemical filtration and reactors pumps that are in this compartment. Ensure that all will still be under water if ATU fails.

    Also
    I prefer the second glass, your distance X, to be one cm lower than first glass pane.
    And then the water level in return chamber to be between 1 and max 5cm below second glass pane (the distance X). The higher the waterlevel, the less bubbles will be created as water falls over this pane.

    @ Neil H

    Great work and I am sure the newbies will be greatfull:thumbup:

    The inlet box also lends itself to the addition of a filter sock , also like the idea of running a seperate top-up chamber the entire length of the sump.
    I was think of having a separate overflow chamber in the cases of power failures and ATU failures.

    Great thread again Neil,

    one thing though, you don't think after the skimmer onto the DSB, there should be one more tier going downwards, to channel the flow to run just over the DSB.

    Hi guys,

    I have a 4ft DT, and was told by members of MASA that to house a DSB my sump would be too small. I also have a partition in my cabinet, so I built a new sump to be housed next to the other. In total, now I have 2 x sumps totalling the width of my 4ft. I have modified them to have a total of 4 compartments. I plan on using the first for skimmer, 2nd and 3rd for DSB and 4th for return pump. Between the 2nd and 3rd the sumps are connected together and I have a 50mm tank connector and the flow between them is gravity driven.

    Questions:
    Will this work ok?
    Should I use one of the DSB compartments as a refugium?
    Must I place reverse lighting on both DSB's?

    yes will work.
    But if you do not use a straight connection, you will find alligning them extremely difficult. Must be 100% perfect. Rather use a S design. Connection out, then 90 elbow, short 50mm pipe, another 90 elbow, connection into second tank. Then any upwards or downwards adjustments are easily sorted.

    DSB if only a DSB do not need light.
    If you keep on one side, above DSB some cheato, yes then you need light only that side.

    Thanks. I have already joined the 2 sumps..... (not an easy affair).... I had to replace 1 panel 3 times because of overtightening the tank connector... (we learn as we go!)
    Found an easy way in the end to mark off the holes in the sump so that they align... My wife's idea and input: After drilling the first sump, rub "LIPSTICK" on the edge of a piece of 50mm pipe, place it through the hole, align the two sumps together and turn the pipe which marks the exact spot where the drilling is to be done on the 2nd sump. Works like engineers blue... hehe

    Tanks for the advice RiaanP... Appreciated.

    Very informative thread.. With regard to the first chamber of the sump design, where the skimmer lives.. Im assuming the overflow of the DT feeds this chamber, the water outlet of the skimmer also feeds this chamber? is this how its suppose to be? Should the water outlet of the skimmer not feed directly into the 2nd chamber?

    no, not on internal skimmers with own feeder pumps, unless you can balance the skimmer feeder pump water flow rate exactly to the return pump. (not possible)

    External skimmers where all water flow from overflow into skimmer, yes, then outlet do go to second chamber.

    So what you saying is that some water coming out of the skimmers outlet will mix with water going into its feeder pump? In other words the skimmer will inevitably reskim some of the water it has just skimmed?

    Yes, if skimmer feeder pump got higher rating than return pump.
    No, if skimmer feeder pump got lower rating than return pump.
    difference between internal and external.

    Thanks Riaan,

    Il be running a TS3 skimmer and a Sicce syncra 2.5 return pump, So the skimmer feeder pump is definitely the more powerful of the two. Is this a problem? I haven't built the sump yet, so im open for suggestions.. As you would have noticed, im classified as plankton, very accurate indeed :)
